HIDE AND LEATHER WORKING MAGHINE.

7 Specification of Letters Patent.

Patent-ed July 9,1918.

Application filed September 20, 1917. Serial 150.18%311 To all! whom it may concern:

lie it known that I, ROBERT F. VVHITKEY, a citizen of the United States, residing at Winchester, in the county of Middlesex and or leather and thereby avoid the necessity of completing the work by hand as is required with the machines new in use. 7 7

As is well known, the hairs with their cells on hides and skins grow in various directions and, as is equally well known, to properly remove these hairs and cells it is necessary to operate the knives orblades against rather than with them or, in other words, figuratively speaking, to war}: against the grain. With the machines now in use equipped with rotary bladed cylinders, or with fixed scraping blades, work on the stock all in one direction only. the hide or skin being operated upon one half at a time, the result being thatit becolnes'necessary to complete the work by manually removing those hairs and cells not removed by the machine blades.

The present invention overcomes to a great extent this defect found in'these inachines by providing for their simultaneously working the stock in opposite directions.

The invention is illustrated hy the accompanying drawings in 'which:

' Figure I is an end view of the machine; Fig.2 is a; side elevation of bar furnished with flanged working blades; f

Fig. 3 is a bottom plan view of the bar shown in Fig.2; 1 V

Fig. 4 is a side elevation partly broken away of a channeledbar furnished with flanged blades;

Fig. 5is a bottom lan bf the bar,

shown in Fig. 4: and

Fig. 6 is a section on the line 6-6 Fig. 4.

Before describing the machine and its operation, it may be stated that the improvement is applicable to all those machines in which a hide or skin is placed on a bed roll, a table, or a bar, which is movable to and away from the work roll, or bladed cylin oted to the frame at 9.

'tion, the spec der, and the feed roll, which movement, as well as the rotation of the rolls, may be accomplished in any of the various well known ways. jIn the present instance the drawings show a frame 1 in which are retatably mounted the work roll 2 with its shaft'li end the feed roll l with its shaft 5 while the bed roll 6 with its shaft 7 is rotatably mounted in swinging arms 8 piv- These rolls are geared in any manner'desired to rotate in thedirections indicated by the several ar rows, it being customary to drive the work roll 2 by a belt (not shown).

This invention consists in adding to the combination described, or to any other similar combination, the vibrating bar 18 with arms 10 which are centrally pivotedito the frame at 11 and pivoted at their inner end 12 to the eccentric (or eccentrics} l3 mounton the frame and driven by the belt 14. in Figs. 1,2 and 3 this bar 10 is shown as furnished with flanged blades 15 mounted on rubber padsor cushions 1 and fastened to the bar by bolts 17 extending through the flanged blades and the cushions into the bar; but any other form of bar may be used.

While the work roll 2 usually found in these machines is working upon the stock in one direction. the blades 15 of the bar 10 are also working upon the. hide 18. part ofthe time in the direction in which the work'roll and bed roll rotate and part of the time in the opposite direction with the result that the stock, after one or more operations thereon, is thoroughly worked out thus making it unnecessary to complete the operation by hand. It is apparent that, in order in mplish the object of the invend of the vibrating bar 10, when this is traveling in the direction in which the bed roll 6 travels, should be greater than that of the bed roll or of the hide supported thereon; V g V InFigs; 4, 5 and 6 is shown a new form of bladed bar comprising the. channeled bar goper IQRvith a narrowed" longitudinal ophing 20 forming interior shoulders 21,

there being disposed within said bar, resting on said shoulders and extending through said opening, a series of flanged blades 22, the flanges of which blades are held against said shoulders by the longitudinal rubber strip 23 and the strip of s ring steel 24 held against said rubber strip y a series of external adjusting screws 25 extending through the bar and each contacting with the spring steel strip. preferably opposite the center of one of the flanged blades.

I claim:

I. In a machine ot' the character described, in combination, a bed roll; a feed roll; a work roll; and a reciprocating bladed bar; the work roll and the reciprocating bladed bar being adjacently disposed at one side of the other rolls; and the bed roll being movable to and a way from the work roll, the reciprocating bar and the teed roll; with means for reciproiigating the bar; and neans t'or accomplishing the movements of the bed roll.

2. In a machine of the character described, in combination, stock supporting lneans; stock feeding means; a work roll; and a reeiprorating bladed bar; the work roll and the reciprrwating bladed bar being adjaeently disposed at one side of the stock feeding means and the stock supporting iueinis; and the bed roll being movable to and away from the storlc supporting means the stock feeding means and the reciprocating bar; With means. for reciprocating the bar and means for accomplishing the movements of the bed roll.

I). In a hide and leather working machine of the character described, a vibrator) bar for working upon a hide, skin, or other stock, coni n'isiug in combination a channeled bar proper having a narrowed opening with interior shoulders adjacent the opening; a series of overlapping flanged blades yieldingly disposed. within the bar with their flanges resting on said shoulders and their blades extending through the opening; a rubber strip disposed ad acent the flanges; a strip of spring steel disposed adjacent the rubber strip; a series of external adjusting screws extending into said bar and engaging said spring steel strip; and means for Vibrating the bar.

t. In a hide and leather working machine of the chararter described, a vibratory bar for working upon a hide, skin, or other stock, comprising in. combination a channeled bar proper having a narrowed opening with interior shoulders adjacent the opening; a series of orcrlapjnng flanged blades 'ieldingly disposed within the bar with their flanges resting on said shoulders and their blades extending through the opening; cushioning means disposed within the bar adjacent the flanges; external adjusting means extending into the bar and engaging the cushioning means; and means fol-vibrating the bar.

5. 1K vibratory bar for workingupon a. hide, skin. or other stock. comprising in combination a channeled bar proper harin a narrowed opening with interior shoulders adjacent the opening; a series of overlapping flanged blades; \'ieldingly disposed within the bar with their flanges resting on said shindders and their blades extendingthrough the opcnin a rubber strip dis posed adjacent .the flanges; a strip of spring steel disposed adjacent the rubber strip; and a series of external adjusting screws extending into said bar and engaging said spring steel strip,

t'. A i'ibratory bar for worliing upon a hide, skin, or other stock, comprising in cone i5 binatjon a channeled bar proper haying a narrowed opening with interior shoulders adjacent the opening; a series of overlapping flanged blades yieldingly disposed within the bar with their flanges resting on 30 said shoulders and their blades extending through the opening; cushioning means disposed within the bar adjacent the flanges; and external adjusting means extending into the bar and engaging the cushioning means. 35

7. A vibratory bar for working upon a hide, skin, or other stock, comprising in eom bination a. channeled bar proper having a narrowed opening with interior shoulders adjacent the openin"; a series of overlapping flanged blades yieldingly disposed within the bar with their flanges resting on said shoulders and their blades extending through the opening; a rubber strip disposed adjacent the flanges; and a strip of spring steel disposed adjacent the rubber strip.

8. A vibratory bar for working upon a. hide, skin, or other stock, comprising in comhination a .ehain eled bar proper having a narrowed opening with interior shoulders adjacent the opening; a series of overlapping flanged blades yieldingly dispmed within the bar with their flanges resting on said shoulders and their blades ,eigtei ding L05 through the opening; andenshioning inners disposed within the bar adjacent the flanges.

In testimony whereof I have atiixed my signature.
